Have more Add Drops and Do not Count certain Add Drops
Make a rule, that if a owner picks up a player overnight, using an Add/Drop, and the players team puts him on the COVID-19 list the next day, before the player even played, then the Add the owner used would not count toward the total allowed, and the owner would get another Add/Drop. This happened to me with Brady Singer this week. Also had more IL slots, since the amount of IL's are becoming too many counting the players put on IL due to testing positive for COVID-19. Go to 10 Team Leagues. There is not enough good hitters and pitchers for all 12 teams to have. Also reward players who pay money to play Yahoo Sports, by guaranteeing them a 1st pick in the first round every so many years.
Thanks for your feedback!
